Kei Truck & Kei Car Import Guide
Tiny 660cc engines, real cargo beds, switchable 4x4 and Japan-spec charm — here is the honest guide to what a kei vehicle is, why Americans keep importing them, and the one thing nobody tells you: whether you can actually put it on the road.
What "Kei" Actually Means
Kei is short for kei-jidosha — literally "light automobile." It is Japan's smallest class of road-legal car, a regulatory box the whole vehicle is engineered to fit inside, and it is the reason these trucks look the way they do.
The rules are strict and specific. Since the standards settled in October 1998, a kei vehicle must be no longer than 3.40 metres (about 11.2 ft), no wider than 1.48 metres (4.9 ft), no taller than 2.0 metres, and powered by an engine of 660cc or less. On top of that sits a long-standing "gentlemen's agreement" among Japanese makers that caps advertised output at 64 PS (about 63 hp) — in practice most kei trucks make somewhere between 40 and 64 hp from a tiny three-cylinder. Stay inside that box and the owner gets cheaper tax, cheaper insurance, and (in much of Japan) a relaxed proof-of-parking rule. Step outside it and the car is taxed as a normal vehicle.
Crucially, "kei" is a size and engine class, not a body style. The same rulebook produces three distinct shapes: the cab-over kei truck with its flat cargo bed, the boxy kei van (a microvan on the same footprint), and the kei car — a tiny hatchback or roadster like the retro Daihatsu Mira Gino. They share engines, plates and tax class; they just carry different things.
“Kei is a regulatory box. Everything about these trucks — the cab-over shape, the 660cc triple, the flat bed — exists to fit inside it.”
The Popular Imports
Four names dominate the kei-truck world, and each has its own reputation. Octane sees all of them come through.
The big four kei trucks
- Daihatsu Hijet — the workhorse. The best-selling kei truck in Japan's history (over 4.5 million sold since 1960), with the longest wheelbase of the group, which buys a longer bed and a more settled ride at speed. Octane regularly stocks the Hijet, including the long-cab "Jumbo."
- Suzuki Carry — the default choice. The most-produced Japanese mini truck ever: the most balanced, the easiest to find, and the cheapest to keep in parts. If you just want a reliable kei truck, this is the safe pick.
- Honda Acty — the off-roader's favourite. The "Attack" trim adds a rear differential lock that no other kei truck offered from the factory, plus a low "granny" crawler gear — genuinely capable on mud, snow and steep ground.
- Subaru Sambar — the oddball, and beloved for it. The only one with a rear-engine, rear-drive layout, which gives a flat load floor, weight over the driven wheels for grip, and a tight turning circle. Subaru built it until early 2012, then licensed the name to Daihatsu.
Beyond those, the Mitsubishi Minicab (also sold as the Nissan Clipper) and the Mazda Scrum (a rebadged Carry) round out the trucks. The same platforms spawn kei vans — the Hijet Cargo, Suzuki Every and Sambar Dias — which trade the open bed for an enclosed box that makes a superb micro-camper or mobile-business shell. And then there are the kei cars: the retro Daihatsu Mira Gino, a Mini-inspired 660cc hatch made from 1999 to 2009 that has become a cult import in its own right. Octane has stocked the Mira Gino alongside its Hijet and HiAce-family vans.
Why Americans Keep Importing Them
A kei truck is the rare vehicle that is cheap, genuinely useful and grin-inducing all at once — and that combination is exactly why demand keeps climbing while the supply ages into legality.
They are cheap to buy and run. A solid 25-year-old kei truck often lands in the rough $5,000–$10,000 range once it is on US soil, sips fuel from a 660cc triple, and is mechanically simple enough to maintain in a home garage. They are absurdly practical. Despite the toy-like footprint, a kei truck carries a 350 kg (770 lb) payload on a flat bed whose dimensions rival a full-size crew-cab's box — ideal for a farm, a ranch, a vineyard, a campground, a warehouse, or a landscaping round.
Many are proper 4x4s. Factory selectable four-wheel drive, low-range gearing, and (on the Acty Attack) a diff lock make these little trucks startlingly good on dirt, snow and trails — which has made them a darling of the overland and hunting crowd. And finally, they are just fun: right-hand drive, a stubby gearshift, Japan-spec quirks and a face only an enthusiast could love. They turn heads at a car meet and do real work on Monday. That dual life — useful tool and weekend character — is the whole appeal.
The Road-Legal Reality (Read This First)
Here is the part that trips people up, so we are going to be blunt about it: importing a kei truck and registering it for the road are two completely separate questions, governed by two different layers of government.
The federal side is settled and nationwide. Once a vehicle is 25 years old it is exempt from the safety and emissions standards that block newer imports, so any kei truck or kei car from the mid-1990s or earlier can legally enter the United States. That part is the same in every state.
Whether you can title and drive it is decided by your state — and the rules vary widely. Roughly three buckets:
- Road-friendly states title and register a 25-year-old kei truck like any other classic import. Texas, Arizona, Oklahoma, Kansas, North Carolina, Washington and several others fall here (rules and lists change — verify before you buy).
- Restricted states allow them only on lower-speed roads or for off-road/farm use. Florida, for example, has limited them to roads posted at 35 mph or below; Louisiana caps them to roads up to 55 mph and bars interstates.
- No-road states won't title them for street use at all — commonly cited examples include California and New York, with several others restricting or refusing registration. In these, a kei truck is a private-property / off-road machine.
These lists genuinely move. Maine and Georgia tightened registrations around 2023; Texas went the other way. Texas DMV offices had briefly refused some kei titles, then in 2024 the state began registering them administratively, and in 2025 Senate Bill 1816 codified kei vehicles as a recognised "miniature vehicle" class, effective September 1, 2025. As things stand, Texas generally lets you title, register and drive a 25-year-old imported kei truck on public roads, with normal insurance and basic equipment (lights, mirrors, seat belts) required; statewide annual safety inspections for non-commercial vehicles ended January 1, 2025, though emissions testing still applies in certain counties.
“Federal law lets a 25-year-old kei truck into the country. Your state decides whether it gets a plate. Always confirm with TxDMV or your own state DMV before you buy.”
None of this is legal advice, and the rules above can change between the day we write this and the day you register. Before committing, confirm current policy with the TxDMV (or your home-state motor-vehicle agency). It is the single most important box to tick — and it is exactly the kind of thing Octane will walk a Texas buyer through.
Importing One
Mechanically the import is simple; the paperwork has one wrinkle worth knowing. Under the US 25-year rule, a kei vehicle that has turned 25 is exempt from FMVSS and EPA standards, so there is no Registered Importer and no compliance bill — it clears on the standard HS-7 and EPA 3520-1 forms at the port, the same as any classic import.
The wrinkle is duty. A kei truck is classified as a light truck under US trade law, which drops it into the infamous 25% "Chicken Tax" rather than the 2.5% rate that passenger cars and vans pay. Kei cars and vans (like a Mira Gino or a Hijet Cargo van) typically fall under the 2.5% passenger rate instead. The classification can be nuanced, so it is worth having a customs broker — or an importer like Octane — handle it correctly rather than guessing. Either way, budget the duty into your number up front; it is the cost most first-time buyers forget.
Add ocean freight, US customs clearance, and then your state's title and registration steps, and you have the full picture. Octane handles the Japan-side sourcing, the export paperwork, shipping and US clearance end to end — and can point Texas buyers at the right registration path on arrival.
Where Can You Take It?
A kei truck is a blank canvas with a flat bed — few vehicles are this easy and this rewarding to build for a specific job. Here is where owners take them.
The Working Mule
The original mission. A 4x4 Hijet or Carry hauls feed, fence posts and tools across a property a side-by-side would struggle with — while costing a fraction of a UTV, carrying more, and being road-legal where the law allows. Add a bed liner, tow hitch and work lights and it earns its keep daily.
Trail and Backcountry
Selectable four-wheel drive, low-range gearing and a diff lock on the Acty Attack make a kei truck a genuinely capable little explorer. Owners fit all-terrain tyres, a mild lift, a bed rack and a rooftop tent and disappear down forest roads no full-size truck can thread.
Micro Overlander
The kei van shines here. A Hijet Cargo, Suzuki Every or Sambar Dias has just enough box for a sleeping platform, a small galley and storage — a true one-person camper that parks anywhere and sips fuel. Truck owners build slide-in bed campers and flat-pack tents for the same effect.
Rolling Storefront
That cab-over face is a marketing gift. Coffee carts, flower trucks, mobile bars, food prep and farmers-market rigs all start as a kei truck or van for the charm, the low running cost and the conversation it starts. Wrap it, shelve out the bed, and it works the weekend markets.
Stanced and Styled
The kei scene loves a clean build: lowered on coilovers, sitting on a set of period wheels, with a tidy wrap and bed accessories. A Sambar or a Mira Gino done right is a genuine show-stand crowd-pleaser that cost less than the wheels on most builds.
Yard and Campus Runner
Where street registration is off the table, kei trucks thrive as off-road utility vehicles — campgrounds, vineyards, large properties, film sets and stadiums use them as nimble, weatherproof, enclosed-cab alternatives to a golf cart, hauling far more in any weather.
Did You Know?
A kei truck's 770 lb bed rivals the cargo box of a full-size crew-cab pickup — on a vehicle barely 11 feet long.
The 64 PS power ceiling isn't a law — it's a voluntary "gentlemen's agreement" between Japanese makers to stop a kei horsepower war.
The Daihatsu Hijet has sold over 4.5 million units since 1960, making it the best-selling kei truck in Japan's history.
The Subaru Sambar was the last kei-compliant vehicle to keep a rear-engine, rear-drive layout — a flat floor and grip the others can't match.
Kei trucks get hit with the 25% "Chicken Tax," a 1964 light-truck tariff — while kei cars and vans usually pay just 2.5%.
The Honda Acty Attack is the only kei truck that came with a factory rear diff lock — the reason off-roaders hunt them down.
"Kei" is a class, not a shape — the same 660cc rulebook builds trucks, vans and cars like the retro Mira Gino.
Texas formally recognised kei trucks as "miniature vehicles" under Senate Bill 1816, effective September 1, 2025.
Frequently Asked
Are kei trucks street legal in the US?
It depends entirely on your state. Federal law lets any 25-year-old kei truck into the country, but each state sets its own road rules. Many states title and register them like a normal classic import; some restrict them to lower-speed or off-road use; and a few, such as California and New York, won't register them for the street at all. Always confirm current policy with your own state's DMV before buying.
Can you register a kei truck in Texas?
Generally yes, for a 25-year-old imported example. Texas began registering kei trucks administratively in 2024, and Senate Bill 1816 formally recognised them as "miniature vehicles" effective September 1, 2025, allowing them to be titled, registered and driven on public roads with insurance and basic equipment. Statewide annual safety inspections for non-commercial vehicles ended January 1, 2025, though emissions testing still applies in some counties. Rules can change, so confirm the current process with the TxDMV.
How much does a kei truck cost?
A solid 25-year-old kei truck typically lands around 5,000 to 10,000 dollars once it is in the US, depending on model, mileage and condition. Older work-ready examples can be found for less, and clean, low-mileage or 4x4 trucks command more. Remember to budget import duty (often 25 percent for trucks), freight and registration on top of the auction price.
What is the best kei truck?
It depends on the job. The Suzuki Carry is the best all-rounder and the easiest to own thanks to parts availability. The Daihatsu Hijet has the longest bed and a more settled ride. The Honda Acty Attack is the off-road pick for its factory rear diff lock. And the Subaru Sambar wins fans with its unique rear-engine layout, flat floor and grip. There is no single best — only the best for your use.
Are kei trucks 4x4?
Many are. Most popular models were offered in both two-wheel-drive and selectable four-wheel-drive versions, and the 4x4 trucks often add low-range gearing for serious traction. The Honda Acty Attack goes further with a factory rear differential lock. If you want a capable off-road or farm truck, look specifically for a 4WD example — not every kei truck has it.
What is the difference between a kei truck, a kei van and a kei car?
They are all the same kei class — same 660cc engine cap, same size limits, same plates and tax. The difference is body style. A kei truck is a cab-over pickup with an open bed; a kei van is an enclosed box on the same footprint; and a kei car is a small hatchback or roadster like the Daihatsu Mira Gino. Pick the body that fits what you want to carry.
What is the 25-year rule?
It is the US federal rule that lets a vehicle 25 or more years old be imported without meeting the modern safety (FMVSS) and emissions standards that block newer imports. It clears on the standard HS-7 and EPA 3520-1 forms with no Registered Importer needed. The 25-year rule governs importation only — it does not guarantee your state will register the vehicle for the road.
Why are kei trucks subject to a 25 percent import tax?
Because a kei truck is classified as a light truck under US trade law, it falls under the 25 percent "Chicken Tax," a tariff dating to 1964. Kei cars and kei vans are usually classified as passenger vehicles and pay the lower 2.5 percent rate. Classification can be nuanced, so it is best handled by a customs broker or an experienced importer.
